Thus, the yield strength, crushing strength, and ultimate strength of a single coal particle with a fixed diameter under uniaxial compression can be approximated as follows: (23) σ dy = 4 P fy π d 2, σ dc = 4 P fc π d 2, σ du = 4 P fu π d 2 where P fy, P fc, and P fu are the forces at the yield point, crushing point, and ultimate point, respectively. It can be generally considered that the tensile strength of the material is .

A crusher transforms rock material into smaller pieces by compressive crushing. The cone crusher is exposed to very large loads throughout the entire life of the crusher. The loading is highly variable and can be described as a combination of cyclic and random loads stretching up to the very high cycle fatigue domain, typically 10^9 cycles, which put high demands on the loadcarrying parts.

Rock failure definition. Stress strain relationships in rocks examined the elastic behavior of rocks, which was largely reversible. Here we deal with permanent deformation. By rock failure, we mean the formation of faults and fracture planes, crushing, and relative motion of individual mineral grains and cements.

Limestone is a rock composed of calcium carbonate (CaCO 3). It is the rock type most commonly used to make crushed stone in the United States. It holds this position because it is widely available and suitable for a greater diversity of uses than any other type of rock. Limestone can be used to make cement. It is the primary ingredient of concrete.
